Answer:

A total of 72 passenger planes came in yesterday.

Explanation:

  Blue Sky International Airport handles passenger to cargo traffic in a ratio of 8 to 5.

  Number of cargo planes landed yesterday = 45

  Number of passenger planes landed = [tex]\frac{8}{5}[/tex] x  Number of cargo planes landed.

 Number of passenger planes landed yesterday = [tex]\frac{8}{5}[/tex] x 45

                                                                               = 8 x 9

                                                                               = 72 passenger planes.

 So a total of 72 passenger planes came in yesterday.

Y intercept means the y-coordinate of the point where the graph crosses the y-axis.

Given equation is:

[tex]-2x+6y=5[/tex]

Let x be 0, as at the y-intercept point, the x-coordinate of that point is always 0.

[tex]-2(0)+6y=5[/tex]

[tex]6y=5[/tex]

y=[tex]\frac{5}{6}[/tex]

Slope-intercept form is y = mx + b

where m is the slope of the line and b is the y-intercept of the line {the number without a variable}

-2x+6y = 5

6y = 2x+5

y= [tex]\frac{2x}{6}+\frac{5}{6}[/tex]

Hence, slope is [tex]\frac{2}{6}or\frac{1}{3}[/tex]

In 4 days it will be 10 and 2/3

To find out how many inches elephant grass will grow in 4 days, multiply the daily growth rate by the number of days. The elephant grass will grow approximately 10 2/3 inches in 4 days.

To find out how many inches of elephant grass will grow in 4 days, we need to multiply the daily growth rate by the number of days. The daily growth rate is 2 2/3 inches. To convert this mixed number to an improper fraction, we multiply the whole number (2) by the denominator (3), which gives us 6. Adding the result to the numerator (2), we get 8. So the daily growth rate is 8/3 inches.

Next, we multiply the daily growth rate by the number of days: 8/3 * 4 = 32/3 inches. To simplify this fraction, we divide the numerator (32) by the denominator (3), which equals 10 with a remainder of 2. So the elephant grass will grow approximately 10 2/3 inches in 4 days.

Answer:

Danny should have sold 124 refreshments every hour for the 3 hours that he helped sell.

Step-by-step explanation:

28° and 152°

let the angle be x then supplementary angle = 3x + 68

Supplementary angles sum to 180° , hence

x + 3x + 68 = 180

4x + 68 = 180 ( subtract 68 from both sides )

4x = 112 ( divide both sides by 4 )

x = [tex]\frac{112}{4}[/tex] = 28

the angles are 28° and ( 3 × 28) + 68 = 84 + 68 = 152°

There are 8 sitcoms that can be recorded on the remaining tape.

To find out how many 30-minute sitcoms can be recorded on the remaining tape, we need to subtract the duration of the existing movie from the maximum capacity of the VHS tape. So, 360 minutes - 120 minutes = 240 minutes remaining. Since each sitcom is 30 minutes long, we can divide the remaining time by 30 to find out the number of sitcoms: 240 minutes ÷ 30 minutes = 8 sitcoms can be recorded on the remaining tape.

The mean of a set of numbers is the average.  In this problem, add all of the numbers together ( negative numbers for the losses) and then divide by the amount of games total.

Here are the numbers we have to use:

+7

-3

-2

+4

+9

the problem would be 7-3-2+4+9=15

Now divide 15 by your total amount of games which would be 5.

15/5=3

The average difference would be 3.  Now a rule in math is to answer a word problem with a sentence.  

The mean difference in scores over the five games played would be 3.

Hope this helps!

Answer:

3

Step-by-step explanation:

Given:

A volleyball team played five games, the team won by 7 points, lost by 3, lost by 2 , won by 4 and won by 9

To find :  the mean difference in scores over the five games

Solution:

Mean basically refers to sum of all observations divided by number of observations.

The mean of scores over the five games refers to sum of all scores divided by 5.

Scores :

won by 7 points means + 7

lost by 3 means - 3

lost by 2 means - 2

won by 4 means + 4

won by 9 means + 9

Therefore,

sum of all scores = 7 - 3 - 2 + 4 + 9 = 15

Also, total number of games played by the team  = 5

So, mean difference in scores over the five games = sum of all scores /  total number of games played by the team = 15 / 5 = 3

Final answer:

To find the length of the shadow cast by a 35-foot building with a 60° angle of elevation to the sun, we can use trigonometry. The shadow is approximately 60.6 feet long.

Explanation:

To find the length of the shadow, we can use the concept of trigonometry. In a right triangle, the opposite side is proportional to the shadow length and the adjacent side is proportional to the height of the building. Using the angle of elevation of 60° and the height of the building as 35 feet, we can set up the trigonometric equation as follows:

tan(60°) = x/35

Solving for x, we get x = 35 * tan(60°) = 60.6 feet. Therefore, the shadow is approximately 60.6 feet long to the nearest tenth of a foot.

Answer:

Option A is correct.

Change in the y-values is 40 and the change in x-values is 1.

Step-by-step explanation:

Let x represents the time in minutes and y represents the temperature(in Fahrenheit).

Given two points on the line graph i.e,

[tex]A(x_1, y_1)= (2 , 150)[/tex]  and  [tex]B (x_2, y_2)= (3, 190)[/tex]

we have to find the change in the y-value and x-value on the graph:

Change in the x-values for the given points is;

[tex](x_2 - x_1)[/tex] = 3 - 2 = 1

Similarly,

Change in the y-values for the given points is;

[tex](y_2 - y_1)[/tex] = 190-150 =40.

Since, the slope or the rate of change of the given line graph is the ratio of the change in the y-value over the change in the x-value i.e, slope = 40.

Therefore, change in the y-values is 40 and the change in x-values is 1.

Answer: There are 12 greatest number of arrangements that she can make and every balloon is used.

Step-by-step explanation:

Since we have given that

Number of white balloons = 24

Number of blue balloons = 60

We need to find the greatest number of arrangements that she can make and every balloon is used.

So, For greatest number of arrangements we will find H.C.F.

So, H.C.F. of 24 and 60 = 12.

Hence, there are 12 greatest number of arrangements that she can make and every balloon is used.
